Radiation level given in article wrong

The article states: "Radiation levels at [reactors] Nos 3 and 4 have been recorded as running at between 3 and 4 millisieverts/hour."

This unfortunately appears to be wrong. Tepco states: "Today [20110317], at approximately 10am [local time], we observed 400mSv/h at the inland side of the Unit 3 reactor building and 100mSv/h at the inland side of the Unit 4 reactor building."
